A `box` is defined as:
`colorspec = "green"`
Spatial Vectors
---------------
-
-* `vector.new([x[, y, z]])`: returns a vector.
- * `x` is a table or the `x` position.
-
+---------------
+* `vector.new(a[, b, c])`: returns a vector:
+ * A copy of `a` if `a` is a vector.
+ * `{x = a, y = b, z = c}`, if all `a, b, c` are defined
* `vector.direction(p1, p2)`: returns a vector
* `vector.distance(p1, p2)`: returns a number
* `vector.length(v)`: returns a number
* `vector.normalize(v)`: returns a vector
-* `vector.round(v)`: returns a vector
+* `vector.round(v)`: returns a vector, each dimension rounded to floor
* `vector.apply(v, func)`: returns a vector
* `vector.equals(v1, v2)`: returns a boolean
* `vector.divide(v, x)`: returns a scaled vector or Schur quotient
Helper functions
------------------
+----------------
* `dump2(obj, name="_", dumped={})`
* Return object serialized as a string, handles reference loops
* `dump(obj, dumped={})`
* `minetest.register_entity(name, prototype table)`
* `minetest.register_abm(abm definition)`
+* `minetest.register_lbm(lbm definition)`
* `minetest.register_node(name, node definition)`
* `minetest.register_tool(name, item definition)`
* `minetest.register_craftitem(name, item definition)`
* `val` is between `0` and `1`; `0` for midnight, `0.5` for midday
* `minetest.get_timeofday()`
* `minetest.get_gametime()`: returns the time, in seconds, since the world was created
+* `minetest.get_day_count()`: returns number days elapsed since world was created,
+ * accounting for time changes.
* `minetest.find_node_near(pos, radius, nodenames)`: returns pos or `nil`
* `radius`: using a maximum metric
* `nodenames`: e.g. `{"ignore", "group:tree"}` or `"default:dirt"`
otherwise returns `nil`.
* The returned table contains the functions `fetch`, `fetch_async` and `fetch_async_get`
described below.
- * Only works at init time.
+ * Only works at init time and must be called from the mod's main scope (not from a function).
* Function only exists if minetest server was built with cURL support.
* **DO NOT ALLOW ANY OTHER MODS TO ACCESS THE RETURNED TABLE, STORE IT IN
A LOCAL VARIABLE!**
* `get_area(id, include_borders, include_data)`: returns the area with the id `id`. (optional) Boolean values `include_borders` and `include_data` control what's copied.
* `get_areas_for_pos(pos, include_borders, include_data)`: returns all areas that contain the position `pos`. (optional) Boolean values `include_borders` and `include_data` control what's copied.
* `get_areas_in_area(edge1, edge2, accept_overlap, include_borders, include_data)`: returns all areas that contain all nodes inside the area specified by `edge1` and `edge2` (inclusive). If `accept_overlap` is true, also areas are returned that have nodes in common with the specified area. (optional) Boolean values `include_borders` and `include_data` control what's copied.
-* `insert_area(edge1, edge2, data)`: inserts an area into the store. Returns the id if successful, nil otherwise. The (inclusive) positions `edge1` and `edge2` describe the area, `data`
-is a string stored with the area.
+* `insert_area(edge1, edge2, data, [id])`: inserts an area into the store. Returns the new area's ID, or nil if the insertion failed. The (inclusive) positions `edge1` and `edge2` describe the area. `data` is a string stored with the area. If passed, `id` will be used as the internal area ID, it must be a unique number between 0 and 2^32-2. If you use the `id` parameter you must always use it, or insertions are likely to fail due to conflicts.
* `reserve(count)`: reserves resources for at most `count` many contained areas. Only needed for efficiency, and only some implementations profit.
* `remove_area(id)`: removes the area with the given id from the store, returns success.
* `set_cache_params(params)`: sets params for the included prefiltering cache. Calling invalidates the cache, so that its elements have to be newly generated.
block_radius = number, -- the radius (in nodes) of the areas the cache generates prefiltered lists for, minimum 16, default 64
limit = number, -- the cache's size, minimum 20, default 1000
}
+* `to_string()`: Experimental. Returns area store serialized as a (binary) string.
+* `to_file(filename)`: Experimental. Like `to_string()`, but writes the data to a file.
+* `from_string(str)`: Experimental. Deserializes string and loads it into the AreaStore. Returns success and, optionally, an error message.
+* `from_file(filename)`: Experimental. Like `from_string()`, but reads the data from a file.
